Biography
Bonnie Isaac is the collection manager for the Section of Botany and co-chair of collections at Carnegie Museum of Natural History. She manages the museum's herbarium, which ranks among the top 25 herbaria in North America.
Isaac received her MS in biological sciences from Youngstown State University in 2000. She was awarded the International Diploma in Herbarium Techniques from The Royal Botanic Gardens in Kew, England in 1988. Isaac completed her BS in biological sciences with an emphasis in plant sciences from Youngstown State University in 1987.
Isaac is the president of the Botanical Society of Western Pennsylvania and an adjunct research scientist for the Hunt Institute for Botanical Documentation at Carnegie Mellon University. She is a past chair of the Pennsylvania Vascular Plant Technical Committee and past recording secretary for the Pennsylvania Rare Plant Forum.
Isaac focuses on the ecology and phytogeography of rare plants, floristics, and herbarium techniques. Her research established that a plant once thought to be in danger of extinction in Pennsylvania, Prenanthes crepidinea, was actually thriving, allowing the plant to be removed from the state’s endangered species list. Other states with populations of Prenanthes crepidinea, a member of the dandelion family commonly called rattlesnake-root, have since worked with Isaac to determine the status of the plant in their regions.
